Rebuttal: Cloud's dark side
Why companies remain reluctant adopting cloud computing?1. Data privacy2. Security3. Licensing4. Applications' redesign
5. Interoperability6. Compliance7. SLAs8. Network monitoring

GRNET cloud service concept
Enabling the Future Service-Oriented InternetI A centralised services provisioning systemI Virtual working enviroment servicesI Services targeted to the academic, scientific, research community…I … while provide support to production / administration services as
well

Current Services
Do we offer any kind of Virtualised/Cloud services?I GRNET Virtual Machine (ViMa) ServiceI GRNET AAI FederationI HellasGrid infrastructureI Pithos online storage service
.ViMa Scope..
.
I Core services hostingI Virtual Private Server (vps) hosting for our clients
. . . . . .
ViMa Service: after some rounds of redux
Prerequisites:I Actual cluster managementI A firm hypervisorI Web frontend for OOB access / power controlI Open architecture :)
Deployment:I KVMI Google's Ganeti project with GRNET NOC contributionsI Custom web frontend in Django (under development)
. . . . . .
Ganeti: Shared-nothing Cluster
I No SPoF in the clusterI Master node: cluster control, master IP addressI Master candidate: cluster configuration copy as master candidateI Simple node: only as node controllerI If master fails: master failover to a master candidate
.Our contribution..

Coming Services
Based on our experience with IaaS we will offer additional SaaS facilities:I Scientific Software as a ServiceI Labs / Science 2.0 Environments as a ServiceI Administration Software as a ServiceI Database as a ServiceI Storage as a ServiceI Grid as a Service (cf. StratusLab)I Private cloud as a ServiceI Hydrib cloud as a ServiceI Disaster recovery as a SI Data archiving / curation as a ServiceI Backup as a Service
. . . . . .
Science 2.0 Environments as a Service
Web 2.0 applications, namely, logging, tagging and social networking, leadto the Open Science model. A new paradigm swift?
I Data-Intensive Science (aka repositories),I Collaborative platforms,I Virtual research environment: Desktop based workflow management
system,I Scientific tools sharing.
. . . . . .
Project facts
I Kick-Off: September 1st,I Budget: 10m€ (cost for a diversity of hardware is anticipated),I Green disaster recovery site is envisaged,I Open-source biased,I Differentiate from currently available commercial services, following
standard (?) commercial APIs,I Quick time to deliver (as always),
. . . . . .
Conclusions
There are many supporting currents in our view of cloud computing:I Economies of scale (favourable economic / market environment)I Lack of sysadmin talentI Quick to market (production)I Long-term experience with providing quality services to the academiaI Excellent cooperation with the public sector / government, possible
to exploit synergies (e.g., disaster recovery).
